Abstract (en)

A method for synthesizing vanadium phosphate comprising pre-mixing a vanadium precursor and a phosphate precursor in a solvent to form a slurry; stirring the slurry at an elevated temperature; adding a carbon source or reducing agent to the slurry; milling the slurry; spray -drying the milled slurry into a powder; and reducing the vanadium precursor to a trivalent vanadium species using a temperature programmed reaction under an inert atmosphere.
